OTTO I-I. JAHNKE AND FRANCIS L. OER, OF DENVER, COLORADO.

WATER-BOISE.

Application filed June 26,

To all whom it may concern:

Be it known that we, O'r'ro H. JAHNKE and FRANors L. Onn, citizens of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Tater-Hoists; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to hoists, and particularly to devices for elevating and discharging water.

One object of the invention is to provide an elevating means in conjunction with the discharging means, which will throw the water away from the elevator instead of toward or into it, as the water is discharged. Another object is to provide means which will effectivelydischarge all of the water away from the elevator. A third object is to include in the driving mechanism means which will in itself serve as a brake for the elevator when power is not being applied.

Briefly, the invention. comprises a shaft carrying sprockets, and an endless carrier equipped with buckets, said shaft also hav ing a gear meshing with a driving worm, said worm serving as a brake for the ele vator. Mounted adjacent the elevator, and associated therewith, is a pair of disks adapted to engage the rising outer edges of the bucket ends to tip the buckets and discharge their contents as they pass said disks. A pan positioned below the disks is connected with a bell crank, one end of which is operated by a cam also mounted on the said sprocket shaft, this device serving to reciprocate the pan laterally in synchronism with the passage of the buckets to throw the rear end of the pan under the edge of each discharging bucket. Means are also provided for adjustment of said disks to withdraw them in order that the elevator may be turned backward to empty the buckets when desired.

of the elevator which will be positioned above the well or stream, from which the water is being lifted.

Fig. 2 is a perspective of the lower p0rtion of the elevator which is suspended in the well or stream.

F 1g. 4 is "a fragmentary plan taken from the line 14, Fig. 5.

Fig. 5 is an end View of one of the buckets and indicates the mounting of the bucket on the endless carrier.

Fig. 6 is a detail, showing one of the disks and the means connected therewith for ad justing the disk.

Fig. 7 is a vertical section on line 7-7, Flg. 6.

Fig. 8 is a vertical'section on line 8'8, Fig. 6.

Fig. 9 is a fragmentaryend elevation, showing in detail the means for tipping the buckets and reciprocating the discharge 21, which extend down into the well and support sprockets 22, fixedly secured to a floating shaft 23. The chains carry buckets 24:, having stub shafts 25 retained in the bucket ends by means of cup washers 26 and nuts 27. The stub shafts 25 are journaled in bosses 28, provided on certain of the links of the'carrier 21. The outer rising edge of each bucket is higher, as indicated at 29, than is the opposite edge. The ends of the buckets gradually increase in width at the top, being widest, as indicated at 30, adjacent the higher edge 29 above described.

A rod 35, carrying disks 36, is journaled in the framework as indicated at 37 This rod. is so positioned as to bring the disks 36 when properly adjusted into position to engage the wide portions 30 at the upper edge 29 of each bucket as the bucket rises, in order to tip it and discharge its contents into the pan or chute 40. The saidportions 3O serve as positive engaging surfaces for the disks 36, and at the same time they throw the water somewhat toward the middle of the bucket so that it is not discharged against the disks 36, but directly into the chute 40. i

The discharge chute 40 is mounted upon the lower arm 41 of a bell crank, which swings on the rod 35 and carries on the free end of its other arm 42 an antifriction roller 43. This roller engages a cam 44, fixed upon the sprocket shaft 18. This cam causes the roller 43 to rise and fall in order to permit the pan to move in beneath the discharge edge 29 of the discharging bucket, and to move out when said bucket has discharged and while the next bucket is rising to discharging position.

As shown in Fig. 9, the cam is allowing the roller 43 and arm 42 to rise, and the pan is being drawn in under the discharge bucket. As the bucket rises a little higher, it will be tipped so as to discharge all of its contents, and the roller 43 will rise toits highest position. The left-hand corner of thecam 44 will then gradually move to and across the roller 43, pressing it into its lowest position and throwing the pan 40 to its limit of motion to the right, thereby permitting the next bucket to rise to the discharge point.

Mounted on one side of each of the disks 36 is a boss 50, carrying an annular groove 51, in which travels a yoke 52 connected with a rod 53, which passes through an eye 54, mounted on the framework 10. A set screw 55 is threaded through the eye 54 to engage the rod 53 and bind it in adjusted position. By this means the disk may be set as desired and then held bytightening the screw 55. The principal object in providing this adjustment is to permit the disks 36 to be moved longitudinally on the rod 35 to clear the buckets in order that they may be moved in a direction opposite from normal to empty them, as in cold weather, to avoid freezing water in them.

The operation, which is clear from the foregoing, consists in applying power to the pulley 12, which is transmitted by worm 16 and gear 18 to the carrier 21. This causes the buckets to rise and to engage the disks 36, whereupon their contents are discharged into the chute 40. This chute is reciprocated, as previously described, to receive all of the contents of the buckets. When power is not being applied to the pulley 12, the worm 16 serves as a brake to the gear 17 and consequently to the entire elevating apparatus. This makes it unnecessary to pro vide any special brake and is highly desirable and advantageous. The high edge 29 of each bucket is provided in order to throw the water sufficiently far to make certain that it falls into pan 40 and to eliminate the necessity of imparting any great amount of reciprocation to the pan.

We claim:

1. In a water hoist, sprockets, an endless conveyer passing thereover, buckets on said conveyer, and means positioned adjacent the said conveyer at one side thereof and projecting into the path of said buckets to engage the tops thereof to discharge the water therefrom, said means being laterally adjustable to withdraw them from the path of said buckets.

2. In a water hoist, sprockets, an endless conveyer passing thereover, buckets on said conveyer, and means positioned, adjacent the said conveyer at one side thereof and projecting into the path of said buckets to engage the tops thereof to discharge the water therefrom, the outer rising edges of said buckets being higher than the opposite edges.

3. In a water hoist, sprockets, an endless conveyer passing thereover, buckets on said conveyer, means positioned adjacent the said conveyer at one side thereof and projecting into the path of said buckets to engage the tops thereof to discharge the water there from, a movable discharge trough positioned below said means, an arm connected with said trough, and a cam adapted to engage said arm to oscillate the same and reciprocate the pan to and from a position beneath the discharge edge of each bucket as it dis-V charges.

4. In a water hoist, a driven shaft, sprock ets thereon, an endless conveyer passing thereover, buckets mounted on said corrveyer, a rod positioned adjacent the upper portion of said conveyer, disks mounted on said rod and in the path of said buckets, in order to engage and discharge the same, a trough positioned beneath said disks, a bell crank on which said trough is mounted, a cam on said driven shaft with which one arm of said bell crank engages to reciprocate said trough.

5. In a water hoist, a driven shaft, sprockets on said shaft, an endless conveyer passing over said sprockets, buckets on said conveyer, a rod positioned adjacent the upper portion of said conveyer, disks adjustably mounted on said rod and adapted to be positioned in the path of said buckets to engage and discharge the same, a bell crank swingingly mounted on'said rod, a trough mounted on one arm of said crank, a roller mounted on the other arm of said crank, a cam fixed on said driven shaft and engaging said roller to reciprocate said trough.

In testimony whereof we afiix our signatures.
